Features of 40 tons gantry hydraulic machine:

Computer optimized structure design, gantry structure, simple, economical and practical.

The hydraulic control adopts a cartridge valve integrated system, with adjustable pressure, stable flow, reliable operation, long service life, and reduced connecting pipelines and leak points.

Independent electrical control system, reliable operation, intuitive movement and convenient maintenance.

Centralized control with buttons, with jog and semi-automatic operation

By operating the control device, two forming processes of fixed stroke and constant pressure can be realized, and functions such as holding pressure and time delay can be realized.

The working pressure of the slide block, the stroke range of the rapid downward movement with no load, and the slow forward movement can be adjusted according to the needs of the process.

Optional accessories for hydraulic presses:

☆ Grating safety protection device

☆ Stroke, pressure, time touch display system

☆ PLC programmable controller

☆ punching buffer device

☆ Floating guide and rolling bracket for mold change

☆ Various forms of mobile workbench

☆ Heating and cooling device of hydraulic system

☆ Lower cylinder of various types of hydraulic press

☆ Fast-stroke flushing device

Application areas of hydraulic presses:

This machine is suitable for the pressing process of plastic materials, such as blanking, bending, flanging, sheet stretching, etc., and can also be engaged in correction, press fitting, grinding wheel molding, cold extrusion metal parts molding, plastic products and powder products. Technology, with punching and buffering device, can be used for punching and blanking processing.

I. Overview of machine performance and structure

1.1. The machine adopts a gantry full steel structure. After vibration aging treatment, the amount of mechanical deformation is small. The frame design is designed with finite elements and has high rigidity and high precision. The gantry hydraulic press table can move up and down, which greatly expands the opening and closing height of the machine and is more convenient to use. It consists of main cylinder, hydraulic power system and electrical system. The workbench is welded with high-quality steel to ensure reliability and durability.

1.2 The tonnage of the pressing cylinder is realized by a piston cylinder. The cylinder body is made of high-quality forged steel. The surface of the piston rod is subjected to intermediate frequency quenching treatment. The main seal of the oil cylinder uses high-quality seals to ensure reliable sealing.

Hydraulic system

2.1 The hydraulic system is installed on the right side of the fuselage.

2.2 The hydraulic system adopts a cartridge integrated system, which is sensitive in movement, reliable in work and good in sealing performance.

2.3 The hydraulic pump station is composed of oil tank, high pressure pump, electric motor, cartridge valve, etc. The oil tank is welded by steel plate and pickled. The oil tank adopts a closed oil tank, the oil suction area and the oil return area are separated, and the oil tank is provided with a cleaning window and a drain plug, which makes cleaning and oil changing convenient. The suction port of the oil pump is equipped with a straight-through oil suction filter to ensure the cleanliness of the oil and the service life of the oil pump and valve.

2.4 The hydraulic system is reliable and sealed without seepage or leakage. The main pipeline adopts flange connection and seismic pipe clamp.

Third, the electrical control system

3.1. Independent electrical cabinet with built-in electrical control systems such as air switches and relays.

3.2. Various alarm signals of hydraulic press, limit switch and press action realize program interlock.

3.3. A centralized control panel is provided, and the necessary operation buttons and selection switches are arranged on the panel.

Fourth, the operation mode of the press

4.1 The press is equipped with jog and semi-automatic operation modes.

4.2 The stroke is adjusted by the stroke control device.

4.3. In addition to completing all the actions of the press, the buttons on the operating platform should also have buttons such as "hand pressing", "return," "stop", and "emergency stop".

Five, security protection

5.1. Set the emergency stop button. Press the emergency stop button and the press will stop immediately.

5.2 The stroke is provided with limit switches at the upper and lower limit positions.

5.3. A hydraulic support safety valve circuit is set in the lower cavity of the piston-type oil cylinder to ensure safety. At the same time, a hydraulic interlock circuit is set to ensure that when the support safety valve is not opened, the upper cavity of the master cylinder cannot output pressure.

Six, equipment working environment

6.1 Power supply: three-phase 380v 50HZ

6.2 Working temperature: 0 ~ 40 ℃
